SASH-FAST'ENER.

SPECIFICATION forming part of Letters Patent No. 369.670, datedSeptember 6, 1887.

Application filed January 29,1887. Serial No. 225,903. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM HANCOCK WEDDINGTON, a citizen of the UnitedStates, residing at Durango, in the county of La Plata and State ofColorado, have invented certain new and useful Improvements in SashLocks and Lifts; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the let-ters and figuresof reference marked thereon, which form a part of this specification. Myinvention relates to that class of devices known as sash locks andlifts,7 and has for its object the production of a reversible lock andlift of novel construction, simple, automati- 1 cally locking, andeasily applied, and that may be cheaply manufactured.

In the drawings, Figure 1 is a front elevation (partly in section) of aportion of a window sash and frame, showing my improvement attachedthereto. Fig. 2 is a view of the lockingbolt. Fig. 3 is a side View(partly in section) of the complete device. Figs. 4, 5, and 6 are detailviews ot' the lock-sheath and the lift.

A is a metal sheath or tube, its inner face, a, being at right angles tothe body of the tube, its opposite or outer end, B, having an obliqueface, b, provided at its upper portion with a parallel oblique-facedstop, c, forming two shoulders, cZ cZ. (Clearly shownin Fig. 5.) The topand bottom of sheath A are provided with longitudinal splines d2.

C is the locking-bolt, having a reduced stem, D, adapted to receive aspiral spring, E.

c and f are shoulders on bolt C and inside of sheath A, respectively,forming two opposing abutments for spiral spring E. Near its outer endsteiii D is recessed, as at g, to receive the end of binding-screw h.

F2 is thelift. (Shown in perspective in Fig. 4 and in front elevation inFig. 6.) It consists of ahead, G, centrally perforated at Z, so as tofit easily on stem I). A screw-threaded hole,

l j, is made in its front face to receive bindingscrew h. The right andleft sides of head G are cut in two parallel oblique planes, H I and HI, each plane ending on the saine central plane and connected to eachother by shoulders 7c Z and 7c Z. One oblique surface may be used on thehead of lifter F2; but I prefer two such surfaces, as herein shown. Byconstructing the right and left hand sides of head G each in twoparallel planes, instead of in one plane, I reduce the friction of theopposing oblique surfaces, and am also enabled thereby to obtain theshoulders or stops 7c Z and k Z, so as to give a certain and positivecheck to the compression of spring E. The same is true, also, of theoblique face b of sheath A and its parallel oblique stop o. The tail orhand piece F of the lift is roughened, as at m, so as to preventslipping from the hand. The outer or exposed end of the device iscovered by a guard, K.

To apply my device to either the upper or the lower sash of a window, Ifirst bore a hole through the sash, as at L, Fig. l, and insert sheath Atherein from the outside of the sash and flush with the same. Thesplines d2 will prevent any rotary motioniof the sheath when in place. Inow insert bolt C, with its spiral spring E, in place, then temporarilyreplace the window-sash in the frame. This will hold the bolt pressedinwardly. Now head Gof the lift is slipped over stem D, and cap or guardK is pushed in place over head G of the lift, (recess g of stem D,screw-hole j of lift, and screwhole in cap K being in alignment.) Thebindingscrew h is now inserted and screwed home. Recesses M for bolt Care bored inthe window-frame at any desired distances apart.

The operation of my device is as follows: To unlock the sash I pull thepart F of the lift outwardly and upward until the shoulder Z or Zengages with shoulder d or tZ of sheath A. This motion withdraws bolt Cfrom recess M in the window-frame. The sash may now be raised by meansof the lift to any desired point and locked there by permitting the liftto resume its downward or normal position when locked, as shown in the.lower part of Fig. I.

This device may be applied to either the right or left hand side of awindow, and may be manufactured and sold with the parts all assembled,ready for use.

Vhat I claim as new, and desire to secure by Letters Patent, is

IOO

The sash lock and lift consisting of sheath A, locking-bolt C, andspiral spring` E, sheath I A having at its outer beveled end a,projecting nib or stop, c, in combination with a lift, FZ, 5 having twooblique surfaces provided with stops or shoulders 7c Z and 7c Z, wherebythe f sash may be unlocked and raised, as herein set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

WILLIAM HANCOCK WEDDINGTON.
